Hello Jan,

When beeps are present....

On the radio unit SIP Status connected/transfering

On the control SIP status idle.

So it looks like when there is a disconnect, the SIP at the radio thinks that it is still going ,,,, maybe??

So, I restart the radio unit and SIP status goes to idle, then try to connect and get beep again, SIP status on control is now unknown (1).

The radio unit SIP status is now at connected/transfering and the beeps are still there.

So, restart both devices, SIP ststus at idle on both.

Connect and all works, connected/transfering on both devices...  So must restart both devices to get SIP status to idle before I can reconnect.

Thanks,
Andrew

Hello Jan,

In fact to get the connect again, I have to restart both radio and control devices, restarting either alone will not allow a connection again after the beeps start.

Thanks,

Hello Jan,

Never had the problem on V2.33 !!

A few more details..

When I try to connect, even after a disconnect, I get the repeated 420Hz tone, one on off cycle every 400ms. The remote unit is visible over IP, Info status etc no problem, even when the beep tone is going. I restarted the remote unit and tried to connect but no luck. I restarted the control unit unit and after several tries was able to connect.

Hope that helps Jan.

PS. I should have put this in the RCC 1258 general discussion,not here!!!

Thanks,
Andrew

I have upgraded from V2.33 to V2.37 on both control and remote units.

The audio functionality seems to be better with V2.36 and 2.37.

All runs fine except when the link drops out,... I get a continuous single tone beep and I cannot connect again. I need to restart both units to get connected again.

Revreted back to V2.36 but the same problem is evident.

Please advise.

Configuration, RRC 1258 / Real Time Modes, Timing Issues

« on: 2011-04-27, 13:06:41 »

Hello,

I am running a RCC-1258MkII control and Radio unit over a 3G network. Settings are; Jitter Buffer 5, Jitter Delay 3, Audio Packet Size 40ms, Audio quality 1. This works fine most of the time for classic audio with some drop outs, but the unit seems to be able recover from a poor connection, it never locks up and I never have to reset anything.

I also run a chirp radar and use the remote site as the receiver. The chirp is a continuous signal of 500Hz to 2500Hz repeated every 1 second. In the chirp receiver (implemented in Spectrum Lab)  the timing of the received signal is very evident as a change in delay of the signal will cause the received chirp to jump in time causing a shift in the received signal. For some reason the system often gets itself very tied up with many time jumps and truncated chirps (especially for tone type signals), so that if I stop the chirp transmission I hear bits of the received chirp ( but not complete chirps) for several seconds after the transmission is stopped. If I start transmitting a chirp again the system still has the same problem. The only way to recover from this situation is to reset the Radio unit, reseting any of the other components in the system will not overcome the lockup problem. Thus, it seems that the radio RCC unit does not handle such realtime signals very well, the time jumps and signal truncation are very evident and recovery from this situation is difficult.

Is it possible to modify the way in which the packet buffering occurs so that for real time signals if there is a packet loss then it is not buffered at all but the time base is kept. There is clearly some issue with tone signals when compared to voice.

Hardware, Cabling, Installations / OUT0 mode "connect"

« on: 2011-03-06, 10:03:11 »

When using the out 0 mode "connect" to activate a relay when connecting to the remote device, I use a small low current relay to drive a much larger relay to turn the DC on to the rig. My setup is solar so need to turn the rig off when it is not in use. All fine.

However, when I turn the rig off by disconnecting the control RCC, the remote relay does not always release so that the rig does not turn off. I traced the problem in the remote RCC to the doide D10 connected between the drain of T1 and the 8-9V. What happens is that when T1 goes open, 12V from the hot side of my small relay feeds current via D10 to the 8-9V line with sufficient current to hold the small relay. This will always happen if an external higher DC voltage is used from the external relay.

Thus, I cut the track between the drain of T1 and D10 to stop this current from the 12V relay going to the 8-9V line and all is fixed.

Further, I cannot see any reason to have D10 connected in such a fashion as it does not seem to serve any purpose.

The RCC control and remote and the relay control work just fine without it. If a larger relay is used with a lower coil resistance then the current may not be enough to hold the relay closed but the coil voltage will be fed back into the remote RCC and on to the 8-9V line, which is probably not desirable.

Ideas ??

General discussion forum / PC CW using DM780 and DTR serial signal

« on: 2010-12-07, 01:14:32 »

I have an Icom 7000 remoted via a Telstra 3G connection... all works fine. I am trying to use CW from my PC using the DTR signal. I have tried all possible configurations but I cannot get the CW to work from the PC. The paddle CW works fine.

In the light of all my experiments, I do not understand what "To activate keying the PC could use the DTR signal in the
virtual USB COM-port delivered by the RRC USB device." means (handbook P53, USB- Control-RCC:) Further I do not understand what "USB DTR as CW" in the IO settings of the control means.

As I am using icon CIV (COM2 mode - logicall parallel with COM 0)I assumed that the DTR signal on the rear comm port would be used but this does not appear to be the case.

Where is the DTR connection for CW on the control RCC?

Hello Frank,

I had a try at this but it seems that it is a bit of an ask...

However, I used a 5v single C/O contact reed relay (very low power) and a small amount of series resistance to cope with the 8V from the box and then used this to switch a high current relay for turning the rig on when the control is connected. Works great. Put a diode across the larger relay coil to avoid reducing the life of the reed relay contacts.

« on: 2010-11-17, 00:23:24 »

Hello Jan and Frank,

Yes,,, I was experimenting with all the settings and accidently left the dns server address out!!!

Putting the dns server address in the control IP Settings and the whole system works extremely well. Without the dns address the system keeps trying to connect just as you indicated Jan, Thanks.

Many thanks.

General discussion forum / Re: DynDNS Update Stopped Working with 2.26

« on: 2010-11-16, 09:49:14 »

Hello,

I am using the Telstra 3G network to access my remote device. The access device is a 3G wireless router which is able to update my remote IP address to DynDNS if the remote wireless device is reset. (the remote IP address is public but not static).

If I ping my DynDNS host name the remote IP address is resolved. Pinging vk3oexxxx.xxxxx.net [132.209.3.131] with 32 bytes of data.

If I use this IP address [132.209.3.131] as the SIP contact in the radio settings on the control device then I can easily connect to the remote device.

If I use the DynDNS host name instead (vk3oexxxx.xxxxx.net ) for the SIP contact then the control device is not able to resolve the remote IP address from DynDNS and I get a SIP Error and 5 sets of increasing tones.

Software is 2.26. I have not tried to use the remote rig device to update DynDNS.

This seems to be at the root of the problem.

Andrew.

Fixed, required a link on the radio board between the 3.5mm centre pin and the SPKR connection on the patch connector.

The remote rig controller works just as claimed, it may take some time to work it all out but it is worth the effort. The networking issues can easily trap an unsuspecting player !!! The tuning using HRD is great! If you are using a 3G connection and the audio is breaking up, ckeck your signal level and get a good antenna, a good radio connection is critical.

I am using 2.26 with DynDns, IC7000, planning on solar power. The IC7000 is easily turned on and off using a relay and the Connect IO, turns the rig off if the connection is lost and on when you connect.

I am looking forward to many hours of fun using a remote site.

Hello Mike,
Thanks for your reply.

However, I have not solved the "no received audio" problem.

Turned off both units and left them overnight, but still the same.

I have checked that the radio received audio does get onto the PCB of the radio unit.

PTT via Icom  HM 151 and transmit voice is good. (I have checked audio with another receiver on air on 14MHz)

HRD control of the IC 7000 works fine as well.

The beep on connect from control to radio units also works.

The yellow light is ON on the aux connector on both units after connect.

I have tried several different audio quality settings (both units always the same) but no change.

I have tried with LAN back to back and no router, also tried with IPsec VPN over 3G and all is still the same, no received audio!

There is data being transfered in both directions as the green LAN lights are blinking after connecting the units.
On the router there is a data transfer rate of about 144kbits/s in both directions. I am now at a loss as to what to do next ?

General discussion forum / No Received Audio

« on: 2010-10-30, 07:11:23 »

I have just received RRC-1258 radio and control units. System works great, IC7000, can transmit with audio with PTT from mic, can control unit with HDR, can even hear the quantisation noise if I use audio quality 0 (alaw 8kHz). Can hear beep on connection and can see IP activity with unit receiving audio packets (can see activity on the router).

But, even connecting the LAN back to back with not router or LAN device  (all works as before) the receive audio is not available.

What connection is missing.

Build Oct 28 2010 10:44:31 for both units.

Any ideas out there ??
